Abstract
A preformed plastic housing encloses a pair of coils and a capacitor of a radio frequency interference (RFI) circuit for an electric motor of a fuel pump. The housing has a base and a cover which, when mated, provide a secure fit between the electrical circuit components and the housing. The preformed housing can accommodate different RFI circuits and is significantly less costly to manufacture than an overmolded RFI module. A grounding strap is connected to the input side of one coil and the capacitor adjacent an input terminal to the circuit to significantly lower the RFI levels in the circuit.
